Are Solar Panels Worth it in Texas? (Detailed Overview)

If you live in Texas and wonder whether solar panels are worth installing, you’ve come to the right place

Residential solar panel installation is reaching an all-time high. In fact, the renewable energy sector grew by 45% in 2020 – the largest annual rate of increase since 1999.

Solar energy continues to be the favorite renewable energy among homeowners, thanks to its ease of use and installation costs.

That’s great and all but what you really want to know is…

Are solar panels worth it in Texas?

Yes, solar panels are worth installing in Texas. In fact, the Global Horizontal Irradiation (GHI) average for Texas is 4.8 kWh/M2, making it one of the most adequate locations within the United States for residential solar panel installation. This stands true whether you own or lease your home.

If you live in a different state within the USA you can find your GHI here.

Are Solar Panels Worth It In Texas?

are solar panels worth it in Texas

If your Texas home has sufficient roof space and is not shaded by a mass of trees, then chances are, installing solar panels will be worth it.

The reason for this is simple – solar panels require a sufficient amount of sun in order to operate at their maximum efficiency.

Texas has more than enough sun.

So, when it comes to sun exposure, there is no need for you to worry, there is an ample amount for your solar panels to absorb.

Let’s talk a bit more about the overall climate in Texas. That way, you’ll be able to figure out whether installing solar panels in this sun-abundant state is worth it, or not.

Understanding The Climate In Texas

Texas has quite a varied climate. It ranges from arid and semi-arid in the West to humid and subtropical in the East.

Generally speaking, the best months for solar production in Texas are between March and September. In March, the sun passes directly over the equator. In June it reaches its furthest north point in the sky, and in September it crosses the equator.

Texas has the ideal weather conditions to produce a consistent amount of energy via a photovoltaic system.

How Much Sunlight Hours Does Texas Receive?

On average Texas receives around 4.8 kWh/M2. However, if you would like to see your exact peak sunlight hours we recommend checking out the map below:

Why would it be beneficial for you to know your area’s peak sunlight hours?

Well, this data (along with your electricity consumption) is critical in understanding what size solar system will suit your needs.

More importantly, you need to know how much a solar system will cost you, and how long will it take to recoup your initial investment.

Once you know this, you can establish whether solar panels are suitable for your situation.

How Much Would A Solar System Cost In Texas?

The cost of your solar system depends on the following criteria:

  1. Your monthly electricity usage
  2. How many peak sunlight hours you receive
  3. The type of solar panels you choose
  4. Which solar brand you decide on

How Much Electricity Do You Use?

First things first, you need to establish what your monthly electricity consumption is. Simply look at your annual electricity bill and divide the kWh usage by 31 to get your monthly consumption.

The average monthly consumption in Texas is 1,140kWh.

How Many Peak Sunlight Hours Do You Receive?

We have already established that Texas receives about 4.8 hours of sunlight a day.

What Type of Solar Panels Do You Want?

Monocrystalline solar panels are by far the smarter more efficient choice and are growing in popularity worldwide, particularly in Germany.

However, they are slightly more expensive.

Your other option would be polycrystalline solar panels – they are less efficient but more affordable.

Which Solar Brand Should You Choose?

The solar brand you choose will have an impact on the overall cost of your solar panel system. Below we have featured a table that breaks down the cost per watt for all the solar companies found in the United States.

Bear in mind, you won’t need such a large solar system. It is very possible that you just need a 2.5 kW solar system to offset your energy consumption.

We will help you figure out your home’s individual solar panel requirements further down in the article. It is likely that solar panels are worth it for you if they cost less than the figures stated below.

How Many Solar Panels Do I Need For My Home in Texas?

In order to figure out how much solar panels will cost for your home in Texas, we need to teach you the formula for sizing your solar system.

You already have all the information stated in the 4 points above.

Now we just have to put it all together.

You will need to use this formula to figure out the number of solar panels your home needs: Monthly electricity usage divided by monthly peak sun hours x 1000. You then divide that answer by the power rating of your proposed solar panel (400 watts, for example).

Using the above formula let’s walk you through the steps you will need to take (simply replace your information where applicable).

Step 1 – Figure out your electricity usage

  • For this example, you use 1,140 kW per month.

Step 2 – What is the monthly peak sun hours in Texas

  • We know that is 4.8 hours a day as an average for the entire Texas, we then multiply that by 31 days to get the monthly value: 4.8 x 31 = 148,8 peak sun hours.

Step 3 – Decide what wattage your solar panels will be and what brand you will use

Step 4 – Apply the formula above

1,140kW divided by 148,8 sun hours = 7.6
7.6 x 1000 = 7600 watts

7600 watts divided by 400 watts = 19

19 Solar panels will need to be installed on your home in Texas.
  • If we buy our panels from Canadian Solar at $2.96 per watt, the total cost of our 7600-watt solar system will amount to $22,496.

As you can see, the cost of your solar system largely depends on your electricity consumption and sun hours.

If you were to live in a place with fewer sun hours than in Texas but you use the same amount of electricity, you would need to install an even bigger solar system to offset your energy usage.

This would mean a higher initial investment, as you’d need more solar panels.

How Long Before Solar Panels Pay Themselves Off In Texas?

This depends on the amount of electricity you consume each month and the size of the solar system you bought.

In Texas, the average monthly electricity consumption is 1,140kWh per month. The average cost per kWh in Texas is 11.96 cents per kWh.

Therefore the average home in Texas could expect to pay about $136,66 a month for electricity.

As already discussed, you would need a 7.6kW (7600 watts) solar system to offset this amount of consumption. Your total cost for a 7.6kW solar system would be $22,496 (before tax incentives).

Texas government allows residential customers to claim a 30 percent tax credit for the purchase and installation of solar systems.

Therefore, your total solar system cost would be $15,748.

$15,748 divided by $136,66 = 115 months.

115 months divided by 12 months = 9.5 years.

It will take a solar panel system 9.5 years to pay itself off, assuming you use around 1,140kWh a month. On average solar panels last between 25 – 30 years.

This means you will enjoy 20 years of free electricity and will save around $32,798 within that time span!

Is it Worth It?

We have given you the ability to determine how much your own home’s solar system would cost, whether solar panels are worth it or not is entirely up to you.

Only you know what you can afford and how much solar savings would benefit your lifestyle.

In our opinion, if you live in Texas, investing in solar panels will be one of the smartest decisions you can make.
